My Thorens TD 124 Mk1 - restoration project

[Ammonite Audio]

That's a ggod choice - enough bulk and mass to help quieten the TD-124, but open so that there is easy access to the underside.

Please forgive my excess of enthusiasm but I find that this plinth is a small work of art.
I took advantage of the sun shining on Milan to take some outdoors shots under natural light.
Under the direct light wood has a beautiful red hue, while the last image was shot with the sun veiled by a cloud, and the wood has hired more brown tones.

WOW! I like that ALOT eugenio!
Im also a bit of a sucker for beautiful timber! That's going to look spot on when the 124 has been installed.

I can't wait to see the finished article.

The turntable is on the way to Rome, to be restored and updated to mk2 specs by Audiosilente.

Thanks to Deano, Dave, Hugo, Nathan and Kevin for for appreciating the plinth

I have another doubt, regarding the plint that is not so heavy and massive.
I will match the turntable to the plinth using the 4 gel mushrooms.

But what about the plinth feet?
I don't have a clear idea on what should be the best choice.
Will it be better to couple through spikes (or other rigid solutions) or decouple with the elastic material feet (like sorbothane or other damping materials)?

My concern relates to the use of double elastic suspension, which could cause unwanted "wave motions" ot the turntable...

If you are going to use compliant mushrooms between the deck and the plinth, use solid feet under the plinth. If you bolt the deck firmly to the plinth without the mushrooms (my recommendation), then some form of isolating support will work. As you have stated, it's not a good idea to have two separate mass/spring systems fighting each other.

Hi Hugo, thank you for your reply.
Reading on the web I've undersood that low mass plinth (like mine) should have the mushrooms and solid feet, while high mass plinth will have better results with the deck directly linked to the plinth and elastic feet under it.
Have you ever tried to "bolt" the turntable frame on a light plinth?
Do you have any foot to recommend me that works fine and is not too expensive?

Your plinth is much higher mass than the usual 'open' types, but not exactly 'high mass'. I've never used a light plinth, so I simply followed Jim Campbell's recommendation to bolt the deck to his heavy plinth.

Unless you are going to place the deck on a heavy platform (which will act as an energy 'sink'), I would not worry too much about feet - small rubber feet would be fine. If you are going to use a heavy support platform, then the plinth needs to be coupled to it, in which case something like small metal or hardwood cones would work well.

The new feet are arrived



...and with the latest arrival there are all the tiles to compose the TD 124 puzzle :-)

Good choice - I've used Stillpoints for years and have not managed to find anything that does what they do with the music. I recommend that you place the deck, with its Stillpoints, on a well-designed and quite massy isolation platform, which will provide a 'sink' for vibrations coming from the deck, and which will stop structure-borne vibration passing up into the deck. Stillpoints are very clever at channelling energy, but they do not isolate, so when used intelligently with a suitable platform, you are onto a winner.
